Pencil Printer Part Two

The refined Pencil Printer part II comes with detailed explanations and a better understand of saving the environment from paper trash and permanency of Ink! In here we see how the lead shavings feed the cartridge toner and prints effortlessly on paper. Mistakes are easily erased, and once the crappy memo is done with…you can erase all the gibberish and re-use the paper. A true test of erasing skills! Designers: Hoyoung Lee, Seunghwa Jeong & Jin-young Yoon

A circular/cylindrical writing instrument being the physical standard seems quite interesting. We’ve worked with everything from hexagonal pencils, to super-thin quills, to rectangular sticks of charcoal……

There are plenty of people who throw away pencil stubs containing an inch of lead. There are plenty of people who throw away pencils that wont sharpen containing 1'' to 6' inches of lead. There are plenty of people who﻿ throw away pencils with bad erasers. There are plenty of people who throw away pencils that snapped in half. There are plenty of people who throw away pencils that split down the center. Add all of that together. Good Idea. Less Trash. Less cartridges.

it could be a good idea but I agree with this post, cause what it seams, you end up wasting more pencil with one page printing than you do with one paper. and almost no one will erase all the page to reuse, if they will, we will need a lot more rubber to erase it all.

I really like the concept of using the lead in it, and even the possibility of erasing. It could do wonders for some illustrators workflow, I’d certainly use it for that purpose. But I still have a few questions: Is this a concept to avoid waste? Because it wastes on pencil. Was it thought as a way to find easy and cheap ‘ink’ when you ran out? Because you might not have an expensive cartridge lying around, but there’s a good chance there is a pencil. is it possible to use just the lead? Like those you buy for mechanic pencils?

Gunnar: I agree with you but I’m pretty that people call those fillings ‘lead’.

what about the fact that you can’t you GRAPHITE, not Lead [Pb], as toner? this doesn’t work as a printing technology! The concept is very beautiful. however someone should have looked up “printing” on wikipedia. I hate to a cynic on a very clean design such as this one, but the main principle is flawed!

If the idea is that it’s for crappy temporary notes, then that’s what people already use pencils for. This thing would use electricity too, and waste pencils, since it apparently strips the wood off to get at the graphite (pencil “lead”).

Well…I have to say that its a bit disappointing that this is the "revised" pencil printer. I mean, nothing major has been solved with these changes, in fact most of them seem good but are really trivial. What happens to the wood from the pencil after you use up a whole pencil every five minutes? it just goes in the trash? Also, while a bit less impractical, I think that the original design was much better that this one. But I must admit that this one wins in terms of portability and convenience. All in all, I'm still a fan of this concept, but it just needs more work.

The earlier model looks as a book. It was interesting. This design is great, minimalistic; I love it. It looks a little bit as a pencil… The aim of the concept, is to use the carbon of the pencil. I think it will be difficult to build a print head using this powder. The more easy way is to re-invent the plotter, using the pencil as printing device. Do you know the Kickstarter site ? You can present your project to find bakers…

This is a great idea and though it is not completely “Green” it’s design does address conservation and existing waste. The reduction of ink usage is a big plus, the revised usage of wasted pencils is a big plus, and the minimal design is a great plus. I haven’t seen it produce graphics, but if it has that capability along with text then it is a great option to bulky, expensive to use, ink printers. The cost of ink is the most prohibitive problem common to current printers. Since more than 60% of printing is of text, black ink or graphite would be the most appropriate. The reduction of paper use is a personal decision problem that has to be addressed with education to the computing populous. The machines we print with is also a personal decision but with minimal options. The more options available will make better choices easier to make economic and green decisions.

Two settings on the same machine. Setting 1 makes 100 copies grinding down a mostly used pencil. Setting 2 makes 1000s+ copies using packaged or user/hobbiest created graphite rods which would cost pennies a foot.

Great idea — don’t get discouraged. It may not necessarily save the Earth but it is an good alternative to toner and ink printers. Keep at it. I love the portability of it — especially when thinking of needs of those who can’t get access to printers readily. Press on!

Has a working prototype been produced? I would love to know if the chemistry behind this could actually work? And like another comment said – surely just putting a pencil in an old style plotter would be similar? Although perhaps slower.

Will this printer EVER be made? If so when? This design has been kicking around the web for over 5 years. Get it on the market, I want one. It would save so much paper in my office, being able to erase and make client changes as they sit there and make remarks/suggestions on what the y want changed in the design. Final prints can be printed from ink printers. E-mail me when it come available, I would prefer a 12 inch wide by 20 inch or longer (roll?) format.
